1. The problem asks to sketch the graph of a relation, but no specific relation is given. 2. To sketch a graph, we need the equation or set of points defining the relation. 3. Common relations include functions like $y = x^2$, $y = \sin x$, or sets of points like $(1,2), (3,4)$. 4. Without a specific relation, we cannot proceed with graphing or analysis. 5. Please provide the explicit relation or equation to sketch its graph.
